of filling for each tuft, said picks being divided into two planes, one pick lying in the lower plane below the stuifers and the other two picks lying in the upper plane above the stufiers. The pile tuft is ordinarily bound in by one of the picks in the upper plane. In

such a fabric the back pick or the one which lies below the stufi'ers' does not contribute directly to holding the tuft in place but serves principally to position the stuifer. It is comactuall Accordi from the tube frame.

mon knowledge that the ordinary Axminster pile tuft is not bound tightly into the cloth and for this reason it may'easily be displaced either in the finishing process subsequent to weaving or in actual use. g

It is an important object of my present invention to employ the same number of picksas are usually present in a three shot Axminster weave and toseparate them by the stufier in the ordinary manner, and to introduce a tuft into the fabric in such a way that the same is bound by all three shots of fillin ugly, in my improved fabric the tuft may extend under the lower pick, over one of the upper picks, under the other ofthe upper picks and then extend upwardly to be out In this way I weave as many tufts per inch asare present in the ordinary Axminster fabric and it is unnecessary to introduce any extra picks or to modify the action of the harness frames which control the binders and the stuifers.

With these and other objects in view which will-appear as thegdescription proceeds, my invention resides in the combination and arrangement of parts hereinafter described and 1 set forth in the claims.

In the accompanying drawings wherein one form of my invention is shown.

Fig. 1 is a vertical section through a portion of the fabric made according to my present invention,

Fig. 2 is a view similar to Fig. 1 but show- .AXMINSTEB W'EAVE 1927. Serial No. 180,731.

ous yarns which enter into the construction of the fabric,

Figs. 3, 4, 5 and 6 illustrate successive steps in the product-ion of the fabric,

Figs. 7 and 8 show modified forms'of the invention.

Referring to Figs. 3 to 6-of the drawings I will describe the preferred method by which the fabric is made, after which the construction of the fabric itself will be readily apparent.

A cloth board 10 forming part of the ordinary 'Axminster loom supports a portion of the woven fabric 11 so as to position the fell thereof with. respect to the tube frame 12. The tube frame may be of the form comprising-a plurality of small yarn tubes arranged side by side through which extend the pile yarns from a spool or other source of supply 13. Only one'of the yarn tubes 14 is shown in the drawings but it is to be understood that there will be one of these yarn tubes for each tuft space across the width of the fabric and there may also be a number of tube frames, depending upon the pattern. For a further understanding of the loom and the ordinary method by which Axminster carpets are I I yarn coming from the tuft tubes 14 lying behind the pick of filling 15'. This much of the operation is similar to that setforth in the aforesaid patents Nos. 490,238 and 712.888. Ordinarily the pile yarn would be.

cut at this point in the cycle of the weave, but by 111 method the cutting is delayed.

With t e tube frame still held in the position shown in Fig. 3 a second shot of filling 17 is laid above the stufi'er S. During this much of the operation the binder B and B have been heldin the position shown in Fig. 3. In the next step in the operation, as shown in Fig. 5, the binders are crossed preparatory v g 'to another dipping of the tube frame, the ing diagrammatically the relation of the varistuifer still being down.

and the stufi'er S, the tube frame being raised so as to pull off the requisite amount of yarn. After the tubcfra'nue has been raised the yarn will be cut by the usual cutters along line 19 so that the rear half of the tuft risesfrom behind the third pick of filling 18.

In the particular form set forth above I' have employed the weave used at the present time in the soscalled three shot Axminster wherein there are three picks of filling lying in two sheds for each tuft of pileyarn. I do not wish to be limited in this particular construction so far as the shedding of the binders or the number of shots of filling is concerned, as I might with equal facility employ .the weave having the binders as set forth in y are all inclosed-between successive crossings of the binders 40 and 41 and that the pile tuft yarn is trained around the shots of filling the aforesaid Patent 712,888, wherein all three shots lie in the same shed. Such a construction is set forth in Fig. 7- wherein it will be'seen that the picks of filling 30, 31 and 32 as in the preferred form, the only difference being that the binders are not crossed twice for each pile tuft.' i

As shown in Ei 18, the second crossing-of the binders inclu es two shots of filling, the

fourth shot being below the stuifer and not necessarilyin contact with the pile tuft.

It is to be understood that'the shotof filling referred to herein in reality comprises two strands, as is usual with lhe needle motion of an Axminster loom.

' From the foregoing it will seen thatIf .have provided, an-Axminster fabric wherein the pile tuft yarn lies in direct contact with severalfor all the shots of filling laid in connection with the pile tuft andthat ,each pick assists in' holding 'the ,tuft firmly in place so as to 'revent accidental removal thereof. It

will urther be seen that thetufts maybe held in lace whether 'the'binders be crossed once or twice for each pile tuft. 4

Having thus deserib d my invention it be seen that changes and modifications may be made therein b those skilled in the art without departin rom the spirit and scope of the invention an I do not wish to be limited to' the details herein disclosed, butjwhat I claim is: 1
